The Capitals had averaged five goals in their previous three games, including a 6-2 victory over New Jersey on Thursday. They didn't keep up that potent pace, but their defensive effort ensured another scuffling outing for the Panthers.

Florida was 1 for 21 on the power play before Boyes scored.

Washington hasn't lost at home to Florida since Dec. 9, 2010.

Situated in the left corner below the goal line, Eric Fehr spotted Chimera open just outside the far post. After receiving the pinpoint centering pass, Chimera faked Montoya out of position before backhanding the puck into the open net for a 1-0 lead 17:12 in.

Neither team scored in the second period, but Brooks Laich's tip-in for Washington was disallowed because of a high-sticking call.

Laich exited the game following a third period collision and didn't return. Trotz said Laich sustained an upper-body injury, but offered no additional information.

Washington held Florida without a shot on its first three power plays, but the Panthers broke that cycle early in the third period.

Peters stopped Sean Bergenheim's close-range attempt, but Boyes put in the rebound 4:27 into the third to make it 1-1.

Peters made his first start since Jan. 19 when he was with Carolina.
